If you want to do it in a really perfect way, help texts aren't the
solution. You'll have to make the options like CONFIG_BLK_DEV_SR no
longer be user visible and select'ed through dummy options like e.g.:
config USB_STORAGE
tristate "USB Mass Storage support"
depends on USB
select SCSI
help
...
config USB_STORAGE_SD
tristate "USB Mass Storage hard disk support"
depends on USB_STORAGE
select BLK_DEV_SD
help
...
config USB_STORAGE_SR
tristate "USB Mass Storage CD/DVD support"
depends on USB_STORAGE
select BLK_DEV_SR
help
...
